ABSTRACT:
A venting device with base and an adjuster supported by the base, and a driver driving the adjuster. The adjuster includes a film vent former moved by the driver between vent formation mode and non-vent formation mode. The adjuster includes an adjustable blade moving from non-vent mode position with the blade on a first side of the film to vent mode position with a segment of the blade positioned on an opposite film side. The blade has a blade segment traveling within a nip region of the film driver of a foam-in-bag dispenser, where the venting device is nestled in a film drive component slot in the nip zone, and an opposite nip zone roller across the film path has a reception groove receiving the blade segment. The blade is contained in a housing shaped to perform a film wrap around prevention function relative to the bag forming assembly.
